如何将数组列表作为数据源添加到devexpress gridcontrol

Question

I have an Arraylist containing an amount of objects. All these Objects have a name, size... Now I want every object to be shown as a row in a grid control. If I write:

gridControl.DataSource = ArrayList;

I get the right amount of rows, but without filling. How can I add the Values of each objects attributes?

ArrayList dataSource = new ArrayList();
dataSource.Clear();

foreach(FileInfo element in dir.GetFiles())
{           
     dataSourceEntry item = new dataSourceEntry();
     item.fileCreateDate = element.CreationTime.Date;
     item.fileName = element.Name;
     item.check = true;
     dataSource.Add(item);
}
gridFiles.DataSource = dataSource;

Answer 1

Because it is hard to extract column's information from ArrayList , I suggest you use generic List<T> instead (or BindingList<T> if you want to track element's changes):

List<dataSourceEntry> dataSource = new List<dataSourceEntry>();

foreach(FileInfo element in dir.GetFiles())
{           
     dataSourceEntry item = new dataSourceEntry();
     item.fileCreateDate = element.CreationTime.Date;
     item.fileName = element.Name;
     item.check = true;
     dataSource.Add(item);
}
gridFiles.DataSource = dataSource;
gridFiles.MainView.PopulateColumns();

PS Anyway, your approach with ArrayList should work correctly when the data source assigned to grid is not empty.
